HDFC Bank — Applied for term insurance

On July 1st 2022 I applied for 2 life plans at hdfc and paid first insurance of 1000 and 1365 under ref HDFC Life Application Numbers[protected] and[protected]. I have submitted all the requested documents through online and sent mail with the same.
However I used to daily receive calls from hdfc executives to provide the same. This was keep on going and no progress.
Hence in the 4th week of July I told if you complete the process by July month, I will cancel those policies. There is no proper response and continuing the same to provide documents
So I sent mail the cancel the policies and refund my amount paid on August 1.
But still they have returned funds saying technical issues and all other ### stories.
Am wondering to open a policy they are taking so much time, if we move for claim think about it.
Pls request then to return my full policy amount of total 2365.
